DEVICES AND SYSTEMS HAVING AC LED CIRCUITS AND METHODS OF DRIVING THE SAME

摘要

A lighting device and system having at least one circuit, the circuit having at least two LEDs connected in series, parallel or anti-parallel configuration and at least one current limiting diode. The device or system may be driven with AC or DC power and may further include a sensor and polarity switching circuit to utilize all LEDs within the circuit when drive by DC power.
